The fixed and variable costs for four potential plant sites for Brent Snyder's Ski Supplies are shown below: a) Graph the total-cost lines for the four potential sites. b) Over what range of annual volume is each location the preferable one (that with lowest expected cost)? Atlanta is (1) Burlington is (2 Cleveland is (3) Denver is (4) c) If expected volume of the ski equipment is 5,000 units (5'. is the best site. (1) never preferable preferable when the volume exceeds 25,000 units preferable when the volume exceeds 3,570 , but is less than 25,000 units (2) preferable when the volume exceeds 3,570 , but is less than 25,000 units preferable when the volume exceeds 25,000 units preferable when the volume exceeds 0 , but less than 5,000 units preferable when the volume exceeds 0 , but is less than 3,570 units preferable when the volume exceeds 0 , but is less than 3,570 units preferable when the volume exceeds 0 , but less than 5,000 units preferable when the volume exceeds 3,570 , but is less than 25,000 units preferable when the volume exceeds 25,000 units never preferable (4) preferable when the volume exceeds 3,570 , but is less than 25,000 units preferable when the volume exceeds 25,000 units preferable when the volume exceeds 0 , but less than 5,000 units preferable when the volume exceeds 0 , but is less than 3,570 units (5) Cleveland preferable when the volume exceeds 0 , but is less than 3,570 units - preferable when Burlington
